CHARLES 1). MGARTHUR, 0F PITTSBURGH, PENNSYLVANIA, ASSIGNOR To BLAW STEEL consrnucrron COMPANY, or HOBOKEN, PENNSYLVANIA, ,A CORPORATION or 7 NEW JERSEY.

To all whom it may concern;

Be it known that I, CHARLES D. MoAR States, residing at Pittsburgh, in the county of 'Allegheny and State of Pennsylvania, have invented certain new and, useful Improvements in Wall-Molds, of. which the followforms for use in the formation of concrete walls, which maybe at any angle. The ob,-

jec'ts of the invention are the provision of a' cheap, slmple, constructlon whlch can be very easily assembled and disassembled, and the provision of a light construction having a maximum degree of strength and stiifness in proportion to itsweight. One embodiment of the invention isillustrated in the accompanying drawings, wherein- Figurell is a front elevation of a wall mold constructed in accordance with my invention, taken through the Wall, on the line II-II As ordinarily constructed, the mold consists ofa series of elongated metal panels A with interposed stiffening and connecting j members 13. In some cases where panels of less length than the panels A are required to complete a wall, other panels C of wood may be employed, such panels being connected] to the members B, however, in the same manner asthe'panels A,-and constituting in effecta modified form of panels. v

' The panels A consist-of sheet metal plates 1 provided at their with the, stiffening angles '2,

and at their end edges with the anglesj3, the

cured to the plates by rivets,-or inany other desired manner. The end angles 3 having-'riveted theretoother angle members 4 having laterally projecting flanges 5 provided with vupturned lips 6. The angle members 4 are at their inner ends spaced away from the angles 3 to provide the slots 7, the function of which will be explained later; The slots or spaces 7 are securedby the use of spacing members 8, but any-other desired means might be employed for securing the necessary slots. e The connecting or stiffening members -B' Specification of Letters Patent.

Intermediate the outturnedflanges 10 is a stiffening strip formed by the'two sheet metal plates ll riveted at their inner ends the inner face of being flush with to the channel '9 and having their outeredges; outturned 'to provide the flanges 12. The members 11 constitute a stifl'ening rib for the 'channels 9, and inaddition cooperate with the locking means hereinafter dew scribed. This locking means consists of pins 13 engaging attheir inner edges the flanges 5 and at their outer edgesjextending through perforations 1 1 in the flanges 12. The plus 13 are provided with slots 14L at their outer ends, and through these slots 14'] extend w dge lfi which bear against the inner faces of theflanges l2. When the wedges are pressed or driven firmly intoposition the pins 13 are cammed inwardly, causing their' A A innerends to clamp the flanges .5 against the face of the channels 9. lips 6' upon the flanges 5 serve to position the ends of the locking pins 13 and to hold.

such ends in position.

The outturned l The outer edges of the plates 11 are pref erably tiedtogether at intervals by means of strips 16 (Fig.1) preferably perforated as indicated at.17, to permit .of the passage of the tie rods to another mold wall 7 opposition to the one illustrated, the channel 9gbe1ng of course correspondingly perfo.-'

rated to permitvof the passage of, the .tie rods therethrough. The 'outturned flanges of the longitudinally extending angles 2 are V alsopreferably' perforated as indicated at 18 placed in,

together, In case a panel of odd-length is required it may be advantageously built up, the panel G consisting of the boards 17 and the-angle members 18 constituting such a built-up structure. "Angle members 18 are provided with laterally extending flanges 19 having upturned lips 20, and the functions accomplished by these parts are the same as with the angle members & heretofore described, the spaces 21 being provided for the reception of the flanges .10 of the channel members 9..

It will be seen that the construction provides an easy and convenient method of assembling and disassembling the panels and stifleners, the parts being readily separated after the removal of the locking pins 13. Only one style or type of stifl'ening members is required, and the panels A may be made all of the same size and construction, except in those instances where panels of odd lengths are required, in which case a board 7 panel corresponding to the panel C can be made which will cooperate with the stiffeners and the ordinary locking means. The

the board panels may be re-used as often as may be desired with the boards of different lengths. The construction when assembled is exceedingly stifl and strong in proportion to its weight, and may be used for walls of large extent and at varying angles, ranging laggingpanel on each side'of the channel iron with its rear face flush with the rear face of the channel, an'angle member secured along the edge of each panel ad acent tending. laterally and fitting against the outer face of the web of the channel ironand with the other flange-spaced away from the panel thus providing a slot to receivethe flange of the channel iron, securing means between the said rib and the lateral flanges of the angle member.

2. In combination in a wall mold, a channel iron having its flanges projecting outwardly from the wall to be formed and hav-. ing a flanges projecting in the same direction, and having laterally extending flanges at its outer edge, a lagging panel on each side of the channel iron with its rear face flush with member secured along the edge of each panel adjacent the channel with one=flange thereof extending laterally and 'fitting against the outer face of the web of the chanmetal angle members 18 as employed with.

outer face of the .web of the channel iron and with the other flange spaced away from the panel to provide a slot to flange of the channel, pins through the flanges of the said rib and engaging the laterally projecting flanges of the angle members, and wedges for holding the pins with respect to nel iron having'its flanges projecting outwardly from the wall to be formed and havmg a longitudinal rib intermediate the having laterally extending flanges at its receive theextending;
